I am trying to measure the distance (in meters) between points that are in the same layer and I would like to account for the distance of meanders in the stream if possible. I was able to calculate linear distance using the measure tool, although I am sure there is an automated and more efficient way of doing that. Is there a way to measure the distance between two points on a flow line?
Here is a photo example: I would like to measure the distance between points, from 1-2, 2-3, 3-4 and so on.
Although flow lines are a natural use-case for linear referencing, building a linearly referenced data set isn't trivial. In this specific case, it isn't necessary so it definitely isn't worth the effort.
If you have a Map with NHD flow lines and a feature class with points that are near or on the flow lines, you can use Split Line at Point (Data Management) - ArcGIS Pro | Documentation to split the flow lines into new segmented flow lines where you can Calculate Geometry Attributes (Data Management) - ArcGIS Pro | Documentation to add the length in units you want. I suggest using selection sets against the NHD flow lines and points to cut down the new feature class to interested/specific flow lines
